UNITED STATES HIRAM E. VICKERS, OF EAST DURHAM, NORTH CAROLINA.

SILKWINDER .ATTACHMENT.

Application filed November 29, 1921.

To a]? whom it may concern -Be it known that. I. H 11mm E. YIc-Knns. a

citizen of the llnited States. residing at East Durham. in the county of Durham and State of North Carolina. have invented new and useful Improvements in Silkwinder Attachments, of which the following is a specification.

This invention relates to improvements in bobbin winding machines. 1

An object of the present invention is the provision of an attachment which is designed to be secured to a bobbin'winding machine for the purpose of treating fiber or other threads, to properly condition them for use. the device being especially adapted v for use with silk fiber.

' the thread to the requisite amount of pressure, to force the liquid into the latter and at thesame time tension the thread, to provide for proper winding.

Withthe above and other objects in view.

the invention further includes the following novelfeatures and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings:

Figure 1 is an end elevation of a bobbin Winding machinewith the invention applied thereto.

Figure 2 is a plan view partly broken away and partly in section, showing the device detached from the machine.

Figure 3 is an elevation of the subject matter of Figure 2.

Figure 4 is a transverse sectional view of the same.

Figure 5 is a detail section illustrating the means for pressing the liquid into the thread and for tensioning the latter as it is wound upon the bobbin.

Referring to the drawings in detail.

wherein like characters of reference denote corresponding parts. there is illustrated a bobbin winding machine which may be of any preferred type and which includes a reel 10 from which the thread 11 is wound upon a bobbin 12. The thread is guided during the winding operation by a builder latter is wound upon the bobbin.

motion which is indicated generally at 13 and whch includes a porcelain or other guide 14. all of which may be of the usual or anv preferred construction.

The type of thread which is commonlv known as silk fiber must be "conditioned? before it is wound upon the bobbin and heretofore various means have been employed to this end. some of which is to spray fiber silk with oil, by hand, or to dip the silk in oil and afterward extract it These methods are open to a number of objections and it is for the purpose of overcoming such objectionable features that the following described invention has been provided.

The invention consists of an elongated trough 15. one end of which is attached to a bar or beam 16. the latter forming a part of the bobbin winding machine. The trough is supported by brackets 17 which engage beneath said trough and are also secured to the bar or beam 16. The trough 15 is di vided into individual compartments 1?. which are adapted to contain oil or other liquid used in the treatment of the thread. one of these troughs being provided for each of the reels 10. Mounted upon a shaft 18. which is rotatable in bearings 19 also secured to the bar or beam 16, are a plurality of rollers or. drums 20. One of these rollers or drums extends within each of the compartments 1? and is adapted to rotate within the liquid contained therein. The rollers are of suflicie'nt. diameter to extend above the top of the trough for contact with the thread 11 as it passes from the reel 10 to the bobbin 12. so that the oil or other liquid will be taken up by the thread as the This method supplies the thread with just a proper amount of oil. so that no surplus oil is taken up which would afterward have to be extracted. I

After passing over the roller 20. the thread 11 passes through a squeezing or pressing device'21. This device is mounted upon the builder motion 13 and is movable therewith as the latter guides the thread upon the bobbin 12. The squeezing or pressing device 21 includes a shaft 22. which is carried by an arm 23. which arm is in turn secured to the builder motion 13, Mounted upon the shaft 22 is a beveled disk 24 which is provided with a sleeve 25. Mounted upon the sleeve 25 is a second beveled disk 26. whose bevel is' arranged in opposition to the bevel of the disk '24 so as to provide a substantially V- shaped groove through which the thread 11 is guided. The disks 24 and 26 are held in yielding engagement by means of a spring 3 27 which surrounds the sleeve As the thread passes through the V-shaped groove formed by the disks 24 and 26. a sufiicient amount of pressure is provided to force the oil or other liquid into the thread so that the latter will be properly conditioned. In addition. the device 21 provides a tensioning device for the thread and the latter will be wound uponthe bobbin in a manner to pre vent slipping. The device 2-1 also enables a greater amount of thread to be wound upon the bobbin than would otherwise be possible.

Mounted upon the end of the shaft'18 is a grooved pulley 28 and passing over this D pulley and a grooved pulley 29 secured upon a shaft 30, is a belt 31. The shaft 30 forms a part of the driving mechanism of the bobbin winding machine, so that as the machine is operated, motion will be imparted to the 5 rollers 20 and the latter will be rotated in i the direction of travel of the thread 11.-

The invention is susceptible of various The combination with a bobbin winding machine including a reel, :1 bobbin and a reel supporting bar, of a cross sectionally substantially semi-circular trough located between the reel and bobbin in the path of the thread, a flange extending from one edge of the trough for attachment to the upper edge of the reel supporting bar, brackets secured to the under face of the bar and extending beneath and shaped to conform to the shape of the trough for supporting the latter, partitions extending transversely within the trough to provide separate liquid compartments, a rotatable shaft extending longitudinally above the trough and rollers mounted upon the shaft and extending into the separate compartments and contacting with the thread.

In testimony whereof I afiix my signature.
